Abstract A flexible full-color micro-LED display with high mechanical robustness was fabricated by printing quantum dots (QDs) on a blue array using standard photolithography. The red and green colors yielded from QDs exhibit better color gamut than conventional filters. light conversion efficiency enhanced adding TiO 2 nanoparticles to the QD-photoresist composite. This successfully mounted va...

Photonic interconnect can provide ultra-high bandwidth with low power consumption, which makes Optical Network-on-Chips (ONoCs) a promising alternative for the nextgeneration high performance chip multiprocessors. To make better use of the optical interconnect, Wavelength Division Multiplexing (WDM) is commonly used to provide high bandwidth and decrease the contention possibility. In this pape...

A wavelength division multiplexing radio-over-fiber (WDM-RoF) system that can support multiband radio signals based on an additional subcentral station (SCS) is proposed and demonstrated in this paper. The dispersion characteristics of the over fiber transmission are explored, we exploit improved structure consisting central (CS), SCS, base stations (BSs) to optimize antidispersion performance ...

Wavelength division multiplexing (WDM) is one of the dominating technologies with high-capacity back bone networks. The cost associated networks given more importance. major issue allocating and managing available resources. To achieve this most efficient algorithms has to be used. We are considering routing lightpath wavelength assignment problem, called as (RWA) problem. optimization fragment...

Light-trail is proposed as a candidate to carry IP traffic over wavelength division multiplexing (WDM) optical networks given its capability of accommodating multi-granularity traffic by time-division multiplexing (TDM). Light-trail’s unidirectional shared-media multicast nature makes it hard to implement distributed access control and restricts that at most one packet transmission can take pla...

Different switching techniques have been proposed to design optical switch architectures. Wave Division Multiplexing (WDM) techniques were extensively investigated to implement switching. Code Division Multiple Access (CDMA) permits multiple users to access bandwidth simultaneously and asynchronously via spread spectrum. This paper presents a non-blocking multiprotocol switch architecture based...

Long haul incoherent optical multichannel communication systems employing N × N Wavelength Division Multiplexing (WDM) in presence of Stimulated Raman Scattering (SRS) and other receiver noises including channel and Amplified Spontaneous Emission (ASE) beat noises is analyzed. Concatenated error control coding techniques are employed to counter system degradation due to these limiting factors. ...

Passive optical networks (PONs) will be the pervasive choice in the design of next-generation access networks. One possible solution to implementing passive optical access networks is to rely on wavelength-division multiplexing (WDM). Here we investigate the problem of providing real-time service to both hard and soft real-time messages in conjunction with a conventional best-effort service in ...

As data traffic increase rapidly, IP over WDM (Wavelength Division Multiplexing) transport will replace conventional SONET transport in current metropolitan area networks. Such networks will require new MAC protocols to efficiently share network bandwidth among multiple network nodes. This research project describes and evaluates a novel Carrier Sense Multiple Access with Idle Detection (CSMA/I...
